High voltage – Power transformer station

Power transformers are of great importance at any high voltage station. This transformer causes the electrical voltage to change in size, which in turn allows connections with varying power supply voltages. Power transformers are transformers connected to the high voltage grid, which have the ability to transform power of more than 10MVA. They are usually placed in a substation. Most of the time, there are three-phase transformers with an operating principle similar to the one of a regular transformer.

Power transformers can work on both sides, this all depends on what side the power is supplied to. For power transformers, the big advantage is the massively high efficiency. In the case of large power transformers, all electrical power that comes into it also comes out as electricity. It is a fact that efficiency increases with size; therefore large power transformers are also the most profitable.
